EMG biofeedback for handwriting disabilities: a critical examination of the literature. 1986

L P Ince, and M S Leon, and D Christidis

A critical examination of the literature on the use of electromyographic (EMG) biofeedback for problems of handwriting is presented. Examined are the procedures, results and conclusions of clinical treatments of writer's cramp and the habilitation of writing. The major flaws in each study are discussed and conclusions drawn from the review are presented, the primary one being that EMG biofeedback of the muscles of the upper extremity has yet to be demonstrated as a treatment of choice for handwriting disabilities. The lack of a sound foundation of data is seen as the main reason for the paucity of investigations in this particular area. Suggestions for further work are offered.

UI MeSH Term Description Entries
D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments. Inotropism,Muscular Contraction,Contraction, Muscle,Contraction, Muscular,Contractions, Muscle,Contractions, Muscular,Inotropisms,Muscle Contractions,Muscular Contractions
D009120 Muscle Cramp A sustained and usually painful contraction of muscle fibers. This may occur as an isolated phenomenon or as a manifestation of an underlying disease process (e.g., UREMIA; HYPOTHYROIDISM; MOTOR NEURON DISEASE; etc.).

D002547 Cerebral Palsy A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR.
